To all wLom, t may concern: A

I citizen of the United States, residing at Plainfield, in the county ofUnionand AState of New Jersey,' have invented new and usefulImprovements in Train-Controllers, of

4which' the following is a specification.

This invention relates 4to devices'ffor automatically .stopping trainsand its object is to provide tripping means applied to the trackand putin action by an attendant or otherqualified party to -operate certain isshut off and lthe brake is set forth in the drawings,

end of a locomotive showing the devicefor operating the throttle andbrake applied 2 is a elevation. Fig. 1 is a perspective view of thetrackshowing the means for operating the trip. Fig. 5. isa plan view Fig. 6is a detail view 'partly in is 'a modified view of the trip operator. l

. The device isv adapted to'be located wit-h in therails of a track andpreferably adjacent to one of the rails and is supplied with' compressedair or other similar means con tained in a tank 10 and adapted to passthrough a pipe 11 to' supply oneor more cylinders 12 in which a pistonworks and is adapted to 'l be vforced backward carrying with it thepiston 13 and connecting rod 14,

-'the latter bengpivoted to a lever 15 in- 16 secured to the ties. 17pivoted to the closed within a bo'x The box 16 has a cover i box at 18and is adapted' tol occupy a horizontal position'or to be thrown up andinthrough which the rod 14 operates and when the air pressure is removedthe .weight of the top will carry the lever 15 downward' and pull thepiston forward.

At one side of a frame' 20 having a lever 21 whose. come in contact withlower end` is adapted to the inclined face 'of .the box top 17 and beVswung backward.

Normally the top end of this lever 21 supportsl a plunger 22 adapted toslide in the frame 20 and lforcev downward by a spring Louis S.MA'r'rox, a'

locomotive whereby the.:

side view of the trip.

The for? the locomotive is secured pivoted at its lower end l 23surrounding'the plunger and confined bei tween the partition 24: and theshoulder'25-fc The upper end of the plunger carries a bar 26 having'vertical pins 27 which play through a, partition 28 and are adapted to.receive the perforated plates on hooks 29 carried by the'en-ds of cords30 and-.31. As -will be seen in Fig. 1, the cord 31 'is arranged toconnect with the end of a cock 32 which controls the iow of steam fromthe j boiler to the oylind'ersand which is provided with a spring 33 toclose same. lVhen the lever 21- strikes the box top and is thrown towarda horizontal position, the plunger 22 is released and descendscarryingthe pins 27 through' the perforations in the partition V29 and allowingthe cord 31 to fly loose and the valve 32 is then closed by means'iof aspring33, thus shutting off the steam supi ply to the cylinders. Thecord 30 controls a valve 31 in the air brake supply pipe 35 and whenthe. hook 29 at the end of cord 30 is released this valve is openedautomatically andthe air supply is furnished to the brake cylinder l36and the brake supply. It will thus be seen that this operation ofshutting off the steam and applying the brake is practicallysimultaneous and it is done auto`- matically and needs the assistance ofnone 1 of the train hands when the inclined top is in its operativeposition.

In Fig.l 7 is shownfa box with the usual top which is adapted Yto belthrown by means of a rod or cord-38 whichmaybe attachedl toa switchlever or other device `which is .vp used in-connectionwith railroads andadapted vto be operated on certain occasions. When `used in connectionwith a switch lthrowing lever, the rody 38 'maybe operated when theswitch is-thrown to elevate the box top 17 and stop vor decrease traintraveling in `that direction.

Itis obvious that t-he parts may .wise Varranged and modified withoutdepart-- ing fromv the essential features above described.

'What' Iclaiin asfnew and desire tosecure by Letters Patent is:

1. In a locomotive controller, the combination of a self closingthrottle valve, a self closingfairbrake valve, a vertical spring pressed,plunger having pins at. its upper end, an element connected at'one endto the self closing throttle valve and havingits op posite end vdetachably .connected to one of be otherv a5A i the speed of 'a 'l thepins, a second element connected at one to the self closing air brakevalve and hpving' its opposite end det-achably connected to another ofsaid pins, a trip below theplunger arranged for holding the plun- 5 ger1n an elevated posit-ion against the action Vof its spring, andanobstruction on the road `f Abed adapted to be 'arranged tostrike thetrip and permit the plunger to descend under the action of itsspringe-nd thereby cause 1`o the pins of the plunger to disconnect fromlsaid first and second namedelements.

2. In a train controller, the combination' with a self closing throttlevalve, of anair brake valve adapted to close automaticallyV 15 a framecarried by the locomotive, a plunger having pins at its upper end, acord for conneting one of the pins with the air brake vulve to hold itopen and having at ono und :i ring fitting over the pin, a second cordcon necting the other pin with the throttle valve to hold it open andhaving at oneV end a ring fitting over the said other pin, a springforcing the plunger downward," a trip beneath the plunger to hold it inits|elevated position, and an obstruction on the track 25 in presence oftwo witnesses.
